问题描述

如何将System.Configuration.ConfigurationManager.AppSettings [x]调用到javascript文件中？



我尝试了什么：



尝试配置管理器和其他参数不成功。

解决方案

你不能调用服务器直接代码，你需要你的服务器代码来渲染一个包含你需要的数据的javascript变量然后使用它



在你的aspx页面上（或者查看）如果你正在使用MVC）

< script> 
 var mySetting ='<％= System.Configuration.ConfigurationManager.AppSettings [MySetting]％>'; 
< / script> 
< script src =/ scripts / test.js>< / script> 

test.js

（document）.ready（function（）{
if（typeof） （mySetting）==undefined）{
//如果您需要检查变量是否已定义，您可以执行此操作
return;
}

//即使你的aspx页面上定义了mySetting，你仍然可以在js文件
//中使用它，只要在定义变量后包含它们
alert（mySetting）;
}）;

How to call System.Configuration.ConfigurationManager.AppSettings["x"] in to javascript file ?

What I have tried:

Tried with config manager and other parameters not succeed.

解决方案

You can't call server-side code directly, you'll need your server code to render a javascript variable that has the data you need and then use that

On your aspx page (or view if you're using MVC)

<script>
    var mySetting = '<%=System.Configuration.ConfigurationManager.AppSettings["MySetting"]%>';
</script>
<script src="/scripts/test.js"></script>

test.js

(document).ready(function () { if (typeof (mySetting) == "undefined"){ // if you need to check if the variable has been defined you can do this return; } // even though mySetting is defined on your aspx page you can still use it in your js files // as long as they are included after the variable is defined alert(mySetting); });
